METHOD AND AUTOMATED SYSTEM FOR ASSISTING IN THE PROGNOSIS OF ALZHEIMER S DISEASE, AND METHOD FOR TRAINING SUCH A SYSTEM

摘要

A method and automated system for assisting in the prognosis of the progress and for assisting in the diagnosis of Alzheimer's disease in patients suffering from mild cognitive impairment (MCI). Also provided is a method for training such a system related to identifying discriminant regions of the brain and using these regions to fine tune the assistance method, based on new known cases. Imaging data (PET or SPECT) is used, representing the cerebral activity in a plurality of spatial zones (voxels). The method then includes a normalization processing of the image data, and analysis of the cerebral activity values read in a selection of voxels forming at least one predetermined discriminant region, defined by its coordinates within a spatial reference system.
